Rollup merge of #64349 - arnohaase:pr_documentation_atomicptr, r=cramertj
documentation for AtomicPtr CAS operations The examples in the documentation for AtomicPtr CAS operations only show code that does *not* perform the CAS operation. I suggest to change them so that they actually do exchange the AtomicPtr's value.
